Power line noise with my new integrated

Hi everyone,

Just added a Belles Soloist 1 integrated to my system.  It sounds fantastic, but it's picking up a lot of power line noise.  I have had many different integrated amps and the worst noise I've ever had is just a small static pop when the A/C kicks on.  Usually, there's no noise at all.  However, with the Belles I'm getting much more power line noise: a buzz every few seconds when the stove is on, a pop when the bathroom fan is switched on, a loud pop with the A/C or heat, and some other random interference.  

I get the same interference with or without a power conditioner (Furman).  I live in an apartment, so a dedicated lines is not possible.  Is it time to try something like a PS Audio Power Plant?  I hate to spend that kind of money just to find out it doesn't make a difference.  Or perhaps there's something that can be done with the Belles to make it less prone to noise?  

Any thought would be welcome.

Thanks, Scott

Bought it used.  Looks to be in fine working order other than the noise, and it sounds great.  I've got a guy locally who does audio repair, so I guess I could have him replace the caps.  I do have pretty terrible power, though, so there might not be any problem with the Belles.  

Thanks, Scott

Would RFI be so closely tied to switching on appliances in the apartment?  I have the dishwasher on right now, and with each cycle there is a static pop (fairly low level) through the speakers.  Would seem to be power line issues rather than RFI, no?  

And, does anyone know of a power regenerator that will allow me to run the Belles (125/250 watts into 8/4ohms) without compromising its performance?

Thanks, Scott

It's used.  Sounds amazing, so I'd love to find a way to calm down the noise issues.  My power is problematic, and I've had a lot of difficulty with tube amps/preamps.  Solid state seems to be much better, but this particular unit is unusually sensitive.  When I adjust the volume with the remote it causes a static pop in the speakers as I depress the button.  Seems odd, no?
